There are countless clinical studies that support the harmful effects that blue light can have for people who are prone to headaches or migraine attacks. Others have pinpointed the exact wavelength to be in and around 480nm; it is exposure to this blue light that leads to high discomfort, a greater perception of pain and throbbing and even enhanced spreading of headache pain across the brain.
